Solution Overview
Problem
Air washer humidifiers have low humidification efficiency due to small water particle sizes, and using hydrophilic resins for disks leads to deformation, while hydrophobic resins reduce humidification efficiency, causing consumer dissatisfaction.
Innovation Solution
An ABS-based resin composition comprising 22.5 to 50% vinyl cyan compound-conjugated diene-based rubber-like polymer-aromatic vinyl compound copolymer, 47.5 to 75% aromatic vinyl compound-vinyl cyan compound copolymer, 1 to 6% polyether ester amide resin, and 1.5 to 3% ethoxylated alkylamine-based antistatic agent, providing superior impact strength, fluidity, and reduced deformation for air washer and humidifier disks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a hydrophilic resin is used as a material of a disk, then moisture adsorption is satisfactorily accomplished, but the resin swells due to moisture adsorption causing disk deformation
Solution Approach 1:
The patent uses a composite resin material consisting of SAN resin (hydrophobic base) and polyether ester amide resin (hydrophilic additive) in specific proportions (0.1-10 wt% polyether ester amide in SAN resin). This composite structure provides both moisture adsorption capability and dimensional stability, resolving the contradiction between hydrophilicity and deformation resistance.
2Shape
If a hydrophobic resin is used to prevent deformation due to swelling, then deformation is prevented, but a humidification amount is decreased due to low surface moisture adsorption rate
Solution Approach 1:
The patent creates local hydrophilic regions within the hydrophobic SAN resin matrix by incorporating polyether ester amide resin particles. This local quality modification allows the disk surface to adsorb moisture effectively while the bulk material maintains its dimensional stability and resistance to deformation.
3Quantity of substance
If a method of coating a hydrophobic resin with a glue, e.g., a hydrophilic resin, is used, then humidification amount is improved, but the hydrophilic resin is detached as use time elapses causing floating matter and contamination
Solution Approach 1:
The patent merges the hydrophobic SAN resin and hydrophilic polyether ester amide resin into a single integrated composite material rather than using separate coating layers. The polyether ester amide resin is incorporated as fine particles (0.1-10 wt%) within the SAN resin matrix, ensuring permanent integration that prevents detachment during use while maintaining continuous humidification performance.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The ABS-based resin composition achieves high humidification efficiency with minimal deformation, maintaining surface hydrophilicity and impact strength, enhancing the performance of air washer and humidifier disks.
Implementation Method 1
the present disclosure relates to an ABS-based resin composition that includes an ABS-based resin, a SAN-based resin, a polyether ester amide resin, and an ethoxylated alkylamine-based antistatic agent and thus is suitable for application to disks of air washers or humidifiers due to properties, such as sufficient humidification provision and less deformation
Implementation Method 2
when a hydrophilic resin is used as a material of a disk, moisture adsorption is satisfactorily accomplished, but the resin swells due to moisture adsorption. Accordingly, the disk may be deformed
